| Risk/Return [Heading] | rr_RiskReturnHeading | Nuveen Dividend Growth Fund | ||||||||
| Objective [Heading] | rr_ObjectiveHeading | Investment Objective | ||||||||
| Objective, Primary [Text Block] | rr_ObjectivePrimaryTextBlock | The investment objective of the Fund is to seek an attractive total return comprised of income from dividends and long-term capital appreciation.
|
||||||||
| Expense [Heading] | rr_ExpenseHeading | Fees and Expenses of the Fund | ||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | The following tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen mutual funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “How You Can Buy and Sell Shares” on page 18 of the Fund’s prospectus and “Purchase and Redemption of Fund Shares” on page S-57 of the Fund’s statement of additional information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in the appendix to the Fund’s prospectus entitled “Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries.” The tables and examples below do not reflect any commissions that shareholders may be required to pay directly to their financial intermediaries when buying or selling Class I shares.

| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | ||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio.

| Expenses Deferred Charges [Text Block] | rr_ExpensesDeferredChargesTextBlock | The contingent deferred sales charge on Class C shares applies only to redemptions within 12 months of purchase. | ||||||||
| Expense Breakpoint Discounts [Text] | rr_ExpenseBreakpointDiscounts | You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen mutual funds. | ||||||||

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | ||||||||
| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
|
||||||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal market conditions, the Fund invests at least 80% of its net assets in dividend-paying common stocks and preferred securities. Companies in certain economic sectors of the market have historically provided higher dividend yields than companies in other sectors and industries. As a result, given the Fund’s focus on dividend-paying securities, the Fund may, from time to time, have a greater exposure to these higher dividend-yield sectors and industries than the broad equity market. The Fund may invest in small-, mid- and large-cap companies. The Fund may invest up to 25% of its net assets in non- U.S. equity securities that are U.S. dollar-denominated.

| Performance Table Narrative | rr_PerformanceTableNarrativeTextBlock | The table below shows the variability of the Fund’s average annual returns and how they compare over the time periods indicated with those of a broad measure of market performance and an index of funds with similar investment objectives. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown for Class A shares only; after-tax returns for other share classes will vary. Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as IRAs or employer-sponsored retirement plans. Both the bar chart and the table assume that all distributions have been reinvested. Performance reflects fee waivers, if any, in effect during the periods presented. If any such waivers had not been in place, returns would have been reduced.

| Nuveen Dividend Growth Fund | Risk Not Insured Depository Institution [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||||||||
| Nuveen Dividend Growth Fund | Active Management Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active Management Risk—The Fund’s sub-adviser actively manages the Fund’s investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund’s sub-adviser may not produce the desired results. This could cause the Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
|
||||||||
| Nuveen Dividend Growth Fund | Cybersecurity Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Fund to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.
|
||||||||
| Nuveen Dividend Growth Fund | Dividend Paying Security Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Dividend-Paying Security Risk—The Fund’s investment in dividend-paying securities could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. Securities of companies with a history of paying dividends may not participate in a broad market advance to the same degree as most other securities, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend. There is no guarantee that the issuers of the securities held by the Fund will declare dividends in the future or that, if declared, they will remain at their current levels or increase over time. Depending on market conditions, dividend paying securities that meet the Fund’s investment objectives may not be widely available or may be concentrated in only a few market sectors. This may limit the ability of the Fund to produce income while remaining diversified.
|
||||||||
| Nuveen Dividend Growth Fund | Equity Security Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Security Risk—Equity securities in the Fund’s portfolio, including common stocks and preferred securities, may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. Holders of common stock generally are subject to more risks than holders of preferred securities because the status of common stockholders upon the bankruptcy of the issuer is subordinated to that of preferred security holders. Given the Fund's focus on dividend-paying securities, the Fund may, from time to time, have a greater exposure to higher dividend-yield sectors and industries than the broad equity market which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.
|
||||||||
| Nuveen Dividend Growth Fund | Foreign Investment Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.
|
||||||||
| Nuveen Dividend Growth Fund | Information Technology Sector Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Information Technology Sector Risk—The Fund currently invests a significant portion of its assets in the information technology sector, although this may change over time. The information technology sector can be significantly affected by changes in, among other things, the supply and demand for specific products and services, the pace of technological development and product obsolescence, market competition, government regulation, and patent and intellectual property rights.
|
||||||||
| Nuveen Dividend Growth Fund | Market Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market Risk—The market value of the Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund’s investments whether or not the Fund invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund’s assets can decline.
|
||||||||
| Nuveen Dividend Growth Fund | Preferred Security Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Preferred Security Risk—Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having fixed interest rates or dividends, which may result in a decline in value in a rising interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.
|
||||||||
| Nuveen Dividend Growth Fund | Small and Mid Cap Company Risk [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Small- and Mid-Cap Company Risk—Securities of small-cap companies involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.
|
||||||||
| Nuveen Dividend Growth Fund | Currency Risks [Member] | ||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||
| Risk [Text Block] | rr_RiskTextBlock | Currency Risk—Even though the non-U.S. securities held by the Fund are traded in U.S. dollars, their prices are typically indirectly influenced by currency fluctuations. Changes in currency exchange rates may affect the Fund’s net asset value, the value of dividends and interest earned, and gains or losses realized on the sale of securities.
